In chemical formulas the number of atoms in a molecule is written as a subscript, so we write H2O for water which has two atoms of hydrogen for each one of oxygen.
(1) A symbol associated with the name of a set to identify a particular subset or element (I) (A) (2) A subscript expression or set of subscript expressions, enclosed in parentheses and used with an array name to identify a particular array element
An occurrence number represented by either an integer, a data- name optionally followed by an integer with the operator + or -, or an index-name optionally followed by an integer with the operator + or -, that identifies a particular element in a table A subscript can be the word ALL when the subscripted identifier is used as a function argument
An integer value, enclosed in parentheses and used with an array name, that specifies the position of an array element See also array, array name, array element
A subscript is a notation that we attach to the lower right of a constant, variable or function name to create a new, but similarly named constant, variable or function For example, in x1, loge, and reffective, the number 1, the constant e, and the word "effective" all serve as subscripts to the variable name, x, the function name, log, and the constant name, r
A smaller than the normal characters, often printed near the base line, e g , 2 in H20
a character or symbol set or printed or written beneath or slightly below and to the side of another character
A scalar integer expression (enclosed in parentheses and appended to the array name) indicating the position of an array element The number of subscripts is the rank of the array See also array element
a character or symbol set or printed or written beneath or slightly below and to the side of another character written or printed below and to one side of another character
), said of marks, figures, or letters (suffixes), written below and usually to the right of other letters to distinguish them; as, a, n, 2, in the symbols Xa, An, Y2
A character printed smaller than standard text and positioned slightly below the baseline; commonly used in mathematical and chemical notation
One or more expressions, each enclosed in brackets, that follow an array name A subscript refers to an element in an array
